Specification of Letters Patent. 2 Patented Oct. 4 1921' Application filed April 6, 1920. Serial No. 371,584.-

In the present patented structures, the calendar shell is formed by assembling a split cylindrical sleeve on a hub structure, an additional strip of metal being disposed beneath the slit in such manner as to provide a groove for receiving a metal tongue forming a fastening means for the end of the fab- To maintain the assembly as just previously set forth, rivets are passed through the edges of the shell or split cylindrical sleeve and through the strip. However, it is found that in winding hot fabric stock on the stock rolls or calendar shells of this construction, the shrinkage of the stock while on the rolls distorts the cylindrical sleeve, either shearing the rivets and ruining the shell, or producing a general collapse of the 35' stock roll.

According to the construction to be herein set forth, the calendar shell or stock roll is formed by assembling two or more telescoped split cylindrical sleeves on a hub structure and forming the fastening groove by depressing the surface of one shell immediately beneath the longitudinal slit in the next succeeding shell. In practice, the slits in the shells are located on a different radii with respect to each other sothat the strongest part of one shell is adjacent the weakest part of the next and the shells are suitably keyed, riveted or otherwise fixedly assembled in this relation.

In the drawings:

- Figure 1 is a perspective view of a stock roll or calendar shell constructed in accordance with the present invention,

Fig. 2 is a'transverse section diametrically of the shell shown in Fig. 1.

F 1g. 3 is a fragmentary longitudinal section along the fastening groove of the stock roll shown in Fig. 1.

In detail:

The stock shell or calendar roll, as herein shown, comprises a hub structure which conslsts of the heads 1 having the peripheral flanges 2, the web 3 and the mandrel receiving flange 4, all of the usual construction, as set forth in my previously mentioned patents. There is ahead 1 at each end of the stock roll or calendar shell and intermediate of these heads are disposed a requisite number of relnforcing spiders 5 supporting a central tube which forms a mandrel opening 6 and the holes 7 provide for ventilation,

having its split 11 disposed medially of the.

depressed portion 10, is a second split sleeve 12, and the edges of the second sleeve are riveted as indicated at 13, to the first sleeve, while the edges of the first sleeve are riveted as indicated at 14 to the body of the second sleeve. In practice, it is preferable to dispose the splits of the two sleeves at diametrically opposite points as shown.

The fabric web 15 is secured to the stock roll or calendar shell in the usual manner by forming a seam 16 at the end of the fabric web and inserting therein the tongue strip 17 which is then inserted in the groove formed by the depressed portion 10.

From the foregoing description, it will be apparent that the stock roll or calendar shell carries a surface built up of laminations of metal which avoid the weaknesses of a single shell and are capable of withstanding distortive strains resulting from shrinking of the stock on the roll without shearing the connecting rivets.

I claim:

A stock roll comprising a hub structure,

I ,a split cylindrical inner tube carried thereby a split tube telescoping over the inner tube and having the joint and split thereof spaced radially from the joint of the first tube, the inner tube being provided exteriorly with a longitudinal groove registering with the split in the outer tube and the edges of the split in the outer tube being out of contact with and projecting over the Walls of the groove in the inner tube, and means for securing the tubes permanently 10 together, said means being located adjacent the splits in the respective tubes.
